Hello, We've got an IP fabric composed with 2 MX204 routers as cores, 2 QFX5110 switches as Provider Edges, and 2 EX2300 as Customer Edges. The MX and the QFX communicate together with BGP underlay and overlay groups, the overlay group use evpn signaling. Everything to run fine except when we want to make Q-in-Q vlans transiting through the VXLAN tunnel (only one VNI : 1001). The Q-in-Q encapsulation comes from the EX2300 switches to the QFX switches (the S-VLAN Q-in-Q tag is also 1001), but on the other end of the tunnel we don't have the Q-in-Q frames coming. We tested some scenarios : for example when we stop the Q-in-Q and just putting VLAN 1001 tagged from the CE switches, the ping is OK through the VXLAN tunnel. We used the pattern 3 from your documentation on the Juniper's website : https://www.juniper.net/documentation/en_US/junos/topics/topic-map/evpn-vxlan-flexible-vlan-tag.html
Do you have some ideas ? Thank you ! Olivier _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
